CONVEYER Filed May ll. 1936 2 Sheets-Sheet 2 I/ Z" Z0 zh Y lmeiza: JOHN W. /TOESYT/- Patented Jan. 11, 1938 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to -conveyers and more particularly to idle conveyers which employ idl rollers.

I n steel mills, by way ofexample, the use of gravity conveyers, or so called ,runways is essential for the transfer of both hot and cold materials. These idle conveyers are made up of rollers with stationary side plates which prevent the material from leaving the rollers. Such conveyers are frequently used for transferring material to shears which are movable for regulating the place the cut is to be made. The movement of these shears results in the lengthening or shortening of the conveyers. This variance makes it difficult to support the rollers of the conveyer so that they will present an even contact surface to the material to be conveyed.

It is among the objects of the present invention to support `a conveyer of the class described in such manner that the surface it presents to the material being conveyed is even; and also to prevent the material from leaving the rollers.

The foregoing and further objects will be apparent after referring to the drawings, in which:

Figure 1 is a plan of the apparatus of the invention.

Figure 2 is a sectional View on the line II'II of Figure 1.

Figure 3 is an enlarged fragmentary plan.

Figure 4 is an enlarged fragmentary elevation partly in section.

Figure 5 is a sectional view on the line V-V of Figure 4.

Referring more particularly to the drawings,

is slidably disposed a shear-housing 3. An elongated screw 4 is screw-threadedly disposed in the shear-housing 3 and rotated in any suitable manner to effect its sliding movement, whereby it may be adjusted with respect to the end-roller 5 of a device which delivers the material to be sheared. Y y

Adjacent the respective upper and lower blades 6 and 1 of the shear, the shear-housing 3 carries a vertically adjustable bed 8 in which there is mounted a rotatable roller 9. VIn order to enable the transfer of the material to be sheared from the end-roller 5 of the device which delivers it to and over the rotatable roller 9 on the shear-housing 3, a conveyer employing idle rollers is provided. 'I'his conveyer is made up of a plurality of parallel shafts I2, each of which lcarries a roller I3. A pair of links I4 connects each end of adjacent pairs of parallel shafts I2. These links I4 are apertured to permit the ends the numeral 2 designates a bed upon which there.

ofthe shafts I2 to extend therethrough and are maintained in spaced parallelism by means of bushings I5. f

Adjacent connected pairs of shafts I2 are connected by substantially rectangulai` frames which are open attheir tops and bottoms. Each of these frames comprises a pair of inner and outer side members Il and I8, respectively, which are beveledV on their lower ends, as shown at I9. The inner and outer side members I1 'and I8, respectively, of the frames are apertured adjacent their lower edges to receive the ends of adjacent linkconnected shafts I2.

The inner side members Il are mounted inside of the pairs of links I4, While the outer side members I8 are mounted outside of the same. The upper edges of the side members I'I and I8 of the frames are extended considerably above the rollers I3 in order to serve as side-guides whereby the material is prevented from leaving the rollers.

The ends of each of the substantially rectangular frames are of different construction. That is: to say, each frame is provided with a shallow end-wall 20 which extends downwardly vbut a slight distance, and with a deeper end-wall 2| which extends downwardly to terminate adjacent the top surfaces of the links I 4. The series of frames are so arranged that the shallow endwall 20 of one abuts the deeper end-wall 2| of another. v

One end of the conveyer is attached, as at 23, to the vertically adjustable bed 8, while the other end is extended over ya roller 25, which is adjacent the end-roller 5 of the device that delivers the material to be sheared. The end of the conveyer which extends o-ver the roller 2.5 depends downwardly into a well 2E where its free end it attached, as at 2l, to a counterweight 28. This weight 28 is disposed in a guideway 29, and its function is to prevent excessive sagging of the conveyer. Despite this, the elements of the conveyer tend to sag and present an uneven surface to the material being conveyed. This tendency is, according to the invention, prevented by the4 contact of the outside surfaces of adjacent endwalls 20 and 2I of the rectangular frames, as: shown at X; and also by the contact of the lower edges of the deeper end-walls 2| with the upper edges of the links I4, as shown at Y. The deeper endfwalls 2|-, by their contact with the upper edges of the links I4, prevent the shafts I2 and rollers I3 from raising when the shear-housing 3 is moved on the bed 2 by the rotation of the elongated screw 4.

While I have shown and described one specific embodiment of my invention, it will be under stood that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined by the following claims.

claim:

1. A conveyer comprising a plurality of parallel shafts, each pair of said shafts being connected together adjacent their ends, a conveyer roll carried by each of said shafts, and means connecting adjacent connected pairs of shafts, said means being disposed adjacent the ends of said con'- ,ffjacent rollers, one end of said frame being defined nected pairs of shafts and comprising a plurality of normally stationary frames, each of said frames being constructed and arranged to provide seats for the ends of said connected pairs of shafts, one end of said conveyer being connected to a normally stationary support, the other end of said conveyer being connected to a tensioning device whereby said conveyer presents a substantially ilat conveying surface.

2. A conveyer comprising a plurality of parallel shafts, each pair of said shafts being connected together adjacent their ends, a conveyer roll carried by each of said shafts, means connecting adjacent connected pairs of shafts, said means being disposed adjacent the ends of said connected pairs of shafts and comprising a'plurality of normally stationary frames, each of said frames being constructed and arranged to provide seats for the ends of said connected pairs of shafts, and interlocking devices on the adjacent ends of said frames, one end of said conveyer being connected to a normally stationary support, the other end of said conveyer being connected to a tensioning device whereby said conveyer presents a substantially at conveying surface.

3. The combination with a roller conveyer employing side-links of a chain link comprising a substantially rectangular frame having spaced apertures for receiving the ends of a pair of adby a downwardly extending shallow end-wall, the other end of said frame being defined by an end wall rwhich extends downwardly to adjacent the top surfaces ofthe side-links of the conveyer.

4. The combination with a roller conveyer employing side-links of a chain link comprising a Substantially rectangular frame having spaced iii apertures for receiving the ends of a pair of'adjacent rollers, one end of said frame being dened by a downwardly extending shallow endwall, the 'other end `of said frame being defined by an end wall which extends downwardly to adf' jacent the top surfaces of the side-'links of the conveyer, said frame having the lower ends of its side members beveled.
